5.1 General
instructions
Protect your instrument against moisture ingress through the following
measures:
•
Use a suitable connection cable (see chapter "
Connecting to
power supply
")
•
Tighten the cable gland or plug connector
•
Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Note:
For safety reasons, the instrument must only be operated within the
ȽÊÅÁËËÁºÄ½ÈÊÇ»½ËË»ÇƼÁÌÁÇÆËƖÇÍ»¹ÆŲƼ¼½Ì¹ÁĽ¼ÁƾÇÊŹÌÁÇÆÇÆ
the process conditions in chapter "
Technical data
" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
•
Active measuring component
•
ÊÇ»½ËËŲÌÌÁÆ¿
•
Process seal
Process conditions in particular are:
•
Process pressure
•
Process temperature
•
Chemical properties of the medium

As a standard feature, the VEGAPULS 6X is separate from the pro-
cess through its plastic antenna encapsulation.
Optionally, the instrument is available with a Second Line of Defense
(SLOD), a second process separation. It is located as gas-tight
leadthrough between the process component and the electronics.
This means additional safety against penetration of the medium fron
the process into the instrument.
